sinuvertebral nerve자료 모음
The sinuvertebral nerves (or meningeal branch of the spinal nerves) are thought to provide innervation of the outer portion of the disc.[9] This nerve is given off by the gray ramus communicans shortly after the ramus arises from the spinal nerve. The nerve courses medially, through the intervertebral foramen back into the spinal canal, where it turns in a cranial direction, around the pedicle, and then moves further medially to run along the PLL (Fig. 4). The nerve provides innervation for the annular fibers of the posterior portion of the disc, the PLL, the epidural blood vessels, the dura mater, and the periosteum. As a result, it is logically assumed to be important in the production of back pain.[11] The anterior portion of the disc is supplied directly by the gray ramus, as is the ALL.[5]
